Patent JP-H06209128-A (JP)
Title: Piezo-actuator
Inventor: USHIJIMA TAKAO
IPC: H01L41/083
Filed: 1993-01-11
Abstract: PURPOSE:To provide a piezo-actuator having high displacement output for a miniaturized device. CONSTITUTION:Multiple element groups 1, 2 are composed by arraying piezo- elements in series while one side element group is inversely arranged on the same side to an intermediate plate 3 to impress respective element groups 1, 2 with inverse phase voltage. In such a constitution, the displacement quantities can be added thereby making the actuator shorter than conventional ones by impressing respective element groups 1, 2 with inverse voltage through the intermediary of the intermediate plate 3 so that the range of application may be enlarged as much while enabling sufficient displacement output to be obtained. Furthermore, the impressed voltage lower than conventional ones can suffice while exercising the effect of improving the electrical efficiency.

Title: Telephone signal transmission/reception method for mobile object communication
Inventor: ITO SADAO
IPC: H04W88/02
Filed: 1993-01-12
Abstract: PURPOSE:To provide a mobile object communication method which can reduce the quantity of transmission/reception information on the telephone signals. CONSTITUTION:Each ratio base station 30 covers plural zones, and each mobile radio equipment 100 uses a radio channel where the telephone signals exist to communicate with the station 30. Then a gateway exchange 20 secures the communication between the station 3 and the equipment 100. Both the station 30 and the equipment 100 store each sample value of many time piece signals obtained by fractionizing the telephone signals at the first stage of calling and then compare each sample value of the time piece signals with each stored one in a busy mode. Then only the identification of the coincident time piece signals is transmitted and the telephone signal is reproduced at the receiver side by the identification signal. Thus the quantity of information to be transmitted is extremely reduced and therefore can be used for the wire transmission. Furthermore the mobile radio transmission power can be reduced.

Filed: 1988-02-01
Abstract: PURPOSE:To reduce a torque ripple by making such a form that the width of a non-polarized pole increases from the inner circumferential side toward the outer circumferential side thereof. CONSTITUTION:A motor is so constituted that a permanent magnet 1 is fixed to a shaft 5 through a yoke 3 and a boss 4 to form a permanent magnet rotor 10. A stator 11 is constituted of a driving coil 9 together with a bracket 7 through a core 8. The permanent magnet rotor 10 is rotatably held by the stator 11 through a bearing 6. At that time, the permanent magnet 1 has four poles, three coil, each pole of the permanent magnet 1 has two non-polarized poles 2, and the poles 2 are arranged symmetrically to the pole center of the permanent magnet 1. The inner side width (h1) and the outer side width (h2) of the non-polarized pole are so formed that the (h2) is larger than the (h1). Accordingly, a torque ripple in operation can be reduced while maintaining desired magnet characteristic of the permanent magnet 1.

Title: Ic package
Inventor: KATO MASAJI
IPC: H01L21/60
Filed: 1990-01-29
Abstract: PURPOSE:To shorten the bonding length at the time of connecting power supply pads and power supply stitches for reduction of the production cost by mounting them parallel to each side of an IC chip and on the same layer, insulating them electrically. CONSTITUTION:Power supply stitches 1, 2 are mounted parallel to each side of an IC chip 6. At that time, the power supply stitches 1, 2 are insulated electrically.

Title: Magnetic recording and reproducing device
Inventor: SENSHIYUU YOUICHIROU
IPC: G11B17/32
Filed: 1987-01-30
Abstract: PURPOSE:To always bring a magnetic sheet and head into good slide contact with each other and to minimize and thin a device in size by traveling the sheet in its travel direction in a gap spreading out in a fan-shape formed with a pair of pads facing both surfaces of the sheet respectively, generating an air pressure and contacting slidably with the head accordingly. CONSTITUTION:By the normal turning direction (a) of the magnetic sheet 1, an airflow flows in between the sheet and head, giving an air pressure on the (d) side of the gap, while creating a negative pressure on the (c) side of the gap, so that the sheet 1 is pressed against the pad 6 side, and hence the recording and reproducing are performed by the head 7. On the other hand, by the reverse travel direction (b) of the sheet, the recording and reproducing are performed by the head 17. Falling-off of the head due to being struck is prevented because the heads 7 and 17 are protruded from the surface by a specific volume respectively to keep a narrow spacing. Consequently, the sheet and head are always brought into good contact with each other, and at the time of stopping the sheet the sheet comes apart from the pad to prevent creep deformation, while a device can be minimized and thinned in size by simple constitution.

Title: Method of controlling tandem system pumping-up power plant
Inventor: NAGAFUJI TOMOTAKE
IPC: F03B15/04
Filed: 1980-02-21
Abstract: PURPOSE: To enable operation mode to be changed without giving abrupt electric power fluctuation to a power system by setting no-load running guide vane opening obtained from separate tests as solenoid closing position.  
     CONSTITUTION: Guide vanes of a water wheel are slightly opened between A and B to flow water into a runner. From point B on, air in an impeller flow path of a pump is gradually exhausted. In this process, the guide vanes of the water wheel are gradually opened and electric power matching with increase of pump input is charged by the output of the water wheel. When the exhaust is completed at point C, a discharge valve of the pump is gradually opened to operate the pump for pumping up. When the pump reaches the normal pumping-up running, the input of the pump is changed over to the system side. When point D is reached, system supply power P becomes equal to the rated input PN of the pump, at point E a governor solenoid is cloed and at point F the guide vanes are fully closed. After the guide vanes are fully closed, a runner is under idle running and mode change to pumping- up running is completed.
